AUXILIARY EQUIPMENT
If the enquiry call was to another Senator extension, that extension must first
be allowed to clear down. The handset should then be replaced momentarily
and the held call will be reconnected when the handset is lifted.
If the enquiry call was to an exchange line, pressing the RECALL button
will reconnect the 'held' line, and hold the line to which the enquiry was
made. You can alternate between the original caller and the third party by
pressing the recall button as required this is known as 'Call Brokering'.
Whilst using call brokering, no enquiry calls may be made unless one of the
call exchange lines is first cleared down. Replacing the handset momentarily
reconnects the held line, and releases the seized line.
All enquiry calls
are
secret from the held exchange line.
If the handset is replaced after a call has been held, the reminder ring back as
described on page 5.4 will be obtained.
An exchange line call can be transferred to another extension by holding the
call and making an enquiry call to the required extension. When the
extension answers and accepts the call, the call will be automatically
transferred by the transferring extension replacing the handset.
An exchange line call which has previously been transferred to the external
extension from another extension, cannot be transferred again, and enquiry
calls cannot be made.
The HOLD and TRANSFER facilities are not available when the
Senator is connected to a
PBX
which uses earth loop recall.
Calls to other extensions can be made as follows:
Lift the handset and dial 0.
ii When system dial tone is heard, dial the required extension number.
m
a) If the required extension is free, system ring tone will be heard.
b) If the required extension is busy, system engaged tone will be heard.
c) If the number of an unequipped extension is dialled, system number
unobtainable tone will be heard.
Incoming calls can be answered by lifting the handset.
An extension connected to an External Extension Adaptor cannot divert
incoming calls, but it may receive diverted calls from another extension.
Telephones connected to External Extensions Adaptors will have similar line
conditions and testing characteristics to those of ordinary DELs.
The Adaptor Units contain integrated circuits mounted on printed circuit
boards and are therefore not suitable for repair in the field. When a unit is
suspected of being faulty it should be replaced with a maintenance spare to
prove the fault.
